I think we really should be digging in the archives and actually finding old things whether it's looking through old computing magazines from the 70s and 80s and 90s. Or looking at technical papers and seeing why do these things fail. What was their good reason? And so the analogy I would use like with bicycles like we don't have the bicycle with the really big wheel anymore because probably was incredibly dangerous. But there are many other things that people tried that are now not such bad ideas. So, so where are the interesting sort of edges in this space where where do you look for inspiration or happiness to get away from tractor beams?"
